He was gifted with a low, melodious, exquisitely modulated voice, and a most engaging and winning manner, and when he set out to picture the simple and easy methods whereby he proposed to make millions, it was next to impossible to resist him. He was like a beautiful, innocent, brilliant child, grown up, endowed with an enchanter's wand, which was forever promising all the kingdoms of the earth to him, but never (as our modern phrase is) delivered the goods. He regarded my father as a king of men, and he had, times without number, been on the very edge of making him, as well as himself, a multifold millionaire. However, President Pierce did what he could for him by giving him the Portuguese mission (after first offering it to my father), and O'Sullivan did excellent work there. But he became interested--abstractly--in some copper-mines in Spain, which, as he clearly demonstrated, could be bought for a song, and would pay a thousand per cent, from the start. Partly to gratify him, and partly with the hope of at least getting his money back, my father finally, in 1858 or 1859, advanced him ten thousand dollars to finance the scheme. I saw the dear old gentleman, a generation later, in New York; he had the same clear, untroubled, tranquil face as of old; his hair, though gray, was as thick and graceful as ever; his manner was as sweet and attractive; but though, in addition to his other accomplishments, he had become an advanced spiritualist, he had not yet coined into bullion his golden imagination. He had forgotten the Spanish copper-mines, and I took care not to remind him of them. Peace to his generous, ardent, and loving soul!
